Since you mentioned that you haven't had the three luxuries (No A/C, No Heat, No Toilet) before...here are a few things that came to my mind that might be something you'll want to look more into before your first trip.
A/C - Consider buying an A/C cover to put on it over long storage periods. Not only will it will help keep out the mud daubers, but also anything that could blow into it and build up during the off periods....leaves are a big one. ADCO and Classic Accessories both carry something along that line. I went one step further and bought the tire covers made by ADCO so that the tires won't rot in the summer sun while parked on the side of my garage. A fin & coil shield might be worth while if you park under low lying trees...just in case. I don't have one of these yet, but one of these day's i'll get to it.
Heater - My first thought was the amount of battery power this could eat up during extended dry camping/boondocking. It might be worth it to think about the dual 6V battery conversion if you've ever wanted to do it. OR Honda/Yamaha generator time....
Toilet - I have this forum and the people i've talked with to thank for all the advice on this subject. I don't know what kind of quality the stock sewer hose would be these days, but the one in my 2k is considered the emergency hose...if I have no other choice, I'll use it. Otherwise, I have a heavy duty sewer hose that is much thicker and doesn't leak. I am also one of the people who have mounted a square vinyl fence post under the frame for carrying this hose and it's accessories outside of my slide storage. Don't forget to pick up some disposable rubber gloves and some sani-wipes...it's just good hygiene practice...nobody needs to get sick from this.
There are also lots of chemicals and detergents available for your black tank and toilet and everyone will have their choice of what to use. As for me, I use a combination of Unique Digest-It and a drop in packet that effervesces when it hits water....which cleans the bowl and when flushed down, works along with the Unique Digest-It. Another item worth mentioning would be a tank rinsing system if it didn't already come with one. For example. you'll find many threads on the camco tornado rotary tank rinse system. With the amount of T.P. that could be going through the tank, it might be worth while to get it installed now instead of later (tanks are still sparkling clean) and your rv service guy will thank you.
. Search the forum on keeping your black tank in good shape, this will be one of the first sources for losing the enjoyment of camping in your TT if not maintained properly.
I hope this helps.
